PROFILE

Bernardo Donadio

Worked on stabilizing and securing the BerriAI/litellm backend by addressing critical reliability and security issues over a two-month period. Focused on Python-based API integration and backend development, delivering targeted bug fixes rather than new features. Improved the Ollama integration by implementing robust JSON parsing and error handling, ensuring the transformation pipeline could gracefully manage malformed or empty responses and correctly process both structured tool calls and standard outputs. Enhanced API security by sanitizing internal provider-prefixed model identifiers from client-facing fields, covering both streaming and non-streaming responses, and added regression tests to maintain compatibility and prevent future regressions.

January 2026: Security and compatibility fix in litellm proxy to sanitize internal provider-prefixed model names from the OpenAI-compatible model field, covering both streaming and non-streaming responses, with regression tests added. This reduces leakage risk and improves client-facing API reliability.

August 2025: Focused on stabilizing the Ollama integration in the BerriAI/litellm project. Delivered a targeted crash fix and robust JSON handling to the Ollama transformation flow, addressing parsing errors, handling empty/invalid content gracefully, and ensuring correct processing of both structured tool calls and standard JSON outputs. This work enhances reliability for tool-based workflows and reduces runtime incidents, contributing to smoother user experiences and lower maintenance overhead.
